At least one physician associates the symptoms with tuberculosis. Some lethal overwhelming infections are reported, aggravating people who already suffer other conditions such as HIV/AIDS.

The signs and symptoms of "activated PI3K Delta Syndrome" are consistent with the following:

- Immunodeficiency

- Lymphadenopathy

- Sinopulmonary infections

- Bronchiectasis

The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development and skeletal system) may be present in certain conditions. Others predispose to autoimmune disease, where the immune system attacks the body's own tissues, or tumours (sometimes specific forms of cancer, such as lymphoma). The nature of the infections, as well as the additional features, may provide clues as to the exact nature of the immune defect.

Adult-onset immunodeficiency syndrome is a provisional name for a newly diagnosed immunodeficiency illness. The name is proposed in the first public study to identify the syndrome. It appears to be chronic and non-contagious, affecting mainly people of Asian descent aged around 50. Cases first started appearing in 2004, primarily in Thailand and Taiwan.

WHIM Syndrome (or Warts, Hypogammaglobulinemia, Immunodeficiency, and Myelokathexis syndrome) is a rare congenital immunodeficiency disorder characterized by chronic noncyclic neutropenia.

The symptoms of CVID vary between people affected. Its main features are hypogammaglobulinemia and recurrent infections. Hypogammaglobulinemia manifests as a significant decrease in the levels of IgG antibodies, usually alongside IgA antibodies; IgM antibody levels are also decreased in about half of people. Infections are a direct result of the low antibody levels in the circulation, which do not adequately protect them against pathogens. The microorganisms that most frequently cause infections in CVID are bacteria Haemophilus influenzae, Streptococcus pneumoniae and Staphylococcus aureus. Pathogens less often isolated from people include Neisseria meningitidis, Pseudomonas aeruginosa and Giardia lamblia. Infections mostly affect the respiratory tract (nose, sinuses, bronchi, lungs) and the ears; they can also occur at other sites, such as the eyes, skin and gastrointestinal tract. These infections respond to antibiotics but can recur upon discontinuation of antibiotics. Bronchiectasis can develop when severe, recurrent pulmonary infections are left untreated.

In addition to infections, people with CVID can develop complications. These include:

- autoimmune manifestations, e.g. pernicious anemia, autoimmune haemolytic anemia (AHA), idiopathic thrombocytopenic purpura (ITP), psoriasis, vitiligo, rheumatoid arthritis, primary hypothyroidism, atrophic gastritis. Autoimmunity is the main type of complication in people with CVID, appearing in some form in up to 50% of individuals;

- malignancies, particularly Non-Hodgkin's lymphoma and gastric carcinoma;

- enteropathy, which manifests with a blunting of intestinal villi and inflammation, and is usually accompanied by symptoms such as abdominal cramps, diarrhea, constipation and, in some cases, malabsorption and weight loss. Symptoms of CVID enteropathy are similar to those of celiac disease, but don't respond to a gluten-free diet. Infectious causes must be excluded before a diagnosis of enteropathy can be made, as people with CVID are more susceptible to intestinal infections, e.g. by Giardia lamblia;

- lymphocytic infiltration of tissues, which can cause enlargement of lymph nodes (lymphadenopathy), of the spleen (splenomegaly) and of the liver (hepatomegaly), as well as the formation of granulomas. In the lung this is known as Granulomatous–lymphocytic interstitial lung disease.

Anxiety and depression can occur as a result of dealing with the other symptoms.

People generally complain of severe fatigue.

Activated PI3K delta syndrome is a primary immunodeficiency disease caused by activating gain of function mutations in the PIK3CD gene. Which encodes the p110δ catalytic subunit of PI3Kδ, APDS-2 (PASLI-R1) is caused by exon-skipping mutations in PIK3R1 which encodes for the regulatory subunit p85α. APDS and APDS-2 affected individuals present with similar symptoms, which include increased susceptibility to airway infections, bronchiectasis and lymphoproliferation.

This condition causes severe infections. it is characterized by elevated immunoglobulins that function poorly.

Other symptoms are:

- Bronchiectasis

- Hepatosplenomegaly

- Pyoderma

- Emphysema

- Diarrhea

Primary immunodeficiencies are disorders in which part of the body's immune system is missing or does not function normally. To be considered a "primary" immunodeficiency, the cause of the immune deficiency must not be secondary in nature (i.e., caused by other disease, drug treatment, or environmental exposure to toxins). Most primary immunodeficiencies are genetic disorders; the majority are diagnosed in children under the age of one, although milder forms may not be recognized until adulthood. While there are over 100 recognized PIDs, most are very rare. About 1 in 500 people in the United States are born with a primary immunodeficiency. Immune deficiencies can result in persistent or recurring infections, autoinflammatory disorders, tumors, and disorders of various organs. There are currently no cures for these conditions; treatment is palliative and consists of managing infections and boosting the immune system.

In reality, immunodeficiency often affects multiple components, with notable examples including severe combined immunodeficiency (which is primary) and acquired immune deficiency syndrome (which is secondary).

AIDS-related complex, or ARC, was introduced after discovery of the HIV (Human Immunodeficiency Virus) when the medical community became aware of the inherent difficulties associated with treating patients suffering from an advanced case of HIV which gave rise to the term Acquired Immune Deficiency Syndrome (AIDS). The necessity for doctors to quickly and accurately understand the special needs of unknown patients suffering from AIDS in an emergency room situation was addressed with the creation of the term ARC.

ARC is "A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating AIDS-related complex ( ARC) from AIDS include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in AIDS; follicular or mixed hyperplasia in ARC lymph nodes, leading to lymphocyte degeneration and depletion more typical of AIDS; evolving succession of histopathological lesions such as localization of Kaposi's sarcoma, signaling the transition to the full-blown AIDS."

Clinical use of this term was widely discontinued by the year 2000 in the United States after having been replaced by modern laboratory criteria.

There are a large number of immunodeficiency syndromes that present clinical and laboratory characteristics of autoimmunity. The decreased ability of the immune system to clear infections in these patients may be responsible for causing autoimmunity through perpetual immune system activation.

One example is common variable immunodeficiency (CVID) where multiple autoimmune diseases are seen, e.g., inflammatory bowel disease, autoimmune thrombocytopenia and autoimmune thyroid disease.

Familial hemophagocytic lymphohistiocytosis, an autosomal recessive primary immunodeficiency, is another example. Pancytopenia, rashes, lymphadenopathy and hepatosplenomegaly are commonly seen in these patients. Presence of multiple uncleared viral infections due to lack of perforin are thought to be responsible.

In addition to chronic and/or recurrent infections many autoimmune diseases including arthritis, autoimmune hemolytic anemia, scleroderma and type 1 diabetes are also seen in X-linked agammaglobulinemia (XLA).

Recurrent bacterial and fungal infections and chronic inflammation of the gut and lungs are seen in chronic granulomatous disease (CGD) as well. CGD is caused by a decreased production of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase by neutrophils.

Hypomorphic RAG mutations are seen in patients with midline granulomatous disease; an autoimmune disorder that is commonly seen in patients with granulomatosis with polyangiitis (Wegner’s disease) and NK/T cell lymphomas.

Wiskott-Aldrich syndrome (WAS) patients also present with eczema, autoimmune manifestations, recurrent bacterial infections and lymphoma.

In autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) also autoimmunity and infections coexist: organ-specific autoimmune manifestations (e.g., hypoparathyroidism and adrenocortical failure) and chronic mucocutaneous candidiasis.

Finally, IgA deficiency is also sometimes associated with the development of autoimmune and atopic phenomena.

Hyper IgM Syndrome Type 2 is a rare disease. Unlike other hyper-IgM syndromes, the Type 2 patients identified thus far did not present with a history of opportunistic infections. One would expect opportunistic infections in any immunodeficiency syndrome. The putative genetic lesion is in the AICDA gene found at 12p13. The patients have three common findings:

- the absence of immunoglobulin class switch recombination

- the lack of immunoglobulin somatic hypermutations, and

- lymph node hyperplasia caused by the presence of giant germinal centers.

Patients exhibit increased susceptibility to bacterial and viral infections, especially from common serotype human papilloma virus, resulting in warts on the hands and feet starting in childhood. Myelokathexis refers to retention (kathexis) of neutrophils in the bone marrow (myelo). In addition, lymphocytes and IgG antibody levels (gammaglobulins) are often deficient.

The bare lymphocyte syndrome, type II (BLS II) is a rare recessive genetic condition in which a group of genes called major histocompatibility complex class II (MHC class II) are not expressed.

The result is that the immune system is severely compromised and cannot effectively fight infection. Clinically, this is similar to severe combined immunodeficiency (SCID), in which lymphocyte precursor cells are improperly formed. As a notable contrast, however, bare lymphocyte syndrome does not result in decreased B- and T-cell counts, as the development of these cells is not impaired.

Diarrhea can be among the associated conditions.

HIES often appears early in life with recurrent staphylococcal and candidal infections, pneumonias, and eczematoid skin.

- Autosomal dominant Hyper-IgE Syndrome caused by STAT3 defects, called Job Syndrome, have characteristic facial, dental, and skeletal abnormalities. Patients with STAT3 HIES may have either delay of or failure in shedding of primary teeth. The characteristic facial features are usually set by age 16. These include facial asymmetry, a prominent forehead, deep-set eyes, a broad nasal bridge, a wide, fleshy nasal tip, and mild prognathism. Additionally, facial skin is rough with prominent pores. Finally, some patients with STAT3 HIES have scoliosis, as well as bones that fracture easily.

- Autosomal recessive

Neutrophil immunodeficiency syndrome is a condition caused by mutations in the Rac2 gene.

LIG4 syndrome (also known as Ligase IV syndrome) is an extremely rare condition caused by mutations in the DNA Ligase IV (LIG4) gene. Some mutations in this gene are associated with a resistance against multiple myeloma and Severe Combined Immunodeficiency. Severity of symptoms depends on the degree of reduced enzymatic activity of Ligase IV or gene expression.

As DNA ligase IV is essential in V(D)J recombination, the mechanism by which immunoglobulins, B cell and T cell receptors are formed, patients with LIG4 syndrome may suffer from less effective or defective V(D)J recombination. Some patients have a severe immunodeficiency characterized by pancytopenia, causing chronic respiratory infections and sinusitis. Clinical features also include Seckel syndrome-like facial abnormalities and microcephaly. Patients also suffer from growth retardation and skin conditions, including photosensitivity, psoriasis and telangiectasia. Although not present in all, patients may also present with hypothyroidism and type II diabetes and possibly malignancies such as acute T-cell leukemia. The clinical phenotype of LIG4 syndrome closely resembles that of Nijmegen breakage syndrome (NBS).

Nuclear factor-kappa B Essential Modulator (NEMO) deficiency syndrome is a rare type of primary immunodeficiency disease that has a highly variable set of symptoms and prognoses. It mainly affects the skin and immune system but has the potential to affect all parts of the body, including the lungs, urinary tract and gastrointestinal tract. It is a monogenetic disease caused by mutation in the IKBKG gene (IKKγ, also known as the NF-κB essential modulator, or NEMO). NEMO is the modulator protein in the IKK inhibitor complex that, when activated, phosphorylates the inhibitor of the NF-κB transcription factors allowing for the translocation of transcription factors into the nucleus.

The link between IKBKG mutations and NEMO deficiency was identified in 1999. IKBKG is located on the X chromosome and is X-linked therefore this disease predominantly affects males, However females may be genetic carriers of certain types of mutations. Other forms of the syndrome involving NEMO-related pathways can be passed on from parent to child in an autosomal dominant manner – this means that a child only has to inherit the faulty gene from one parent to develop the condition. This autosomal dominant type of NEMO deficiency syndrome can affect both boys and girls.

It is characterized by recurrent "cold" staphylococcal infections, unusual eczema-like skin rashes, severe lung infections that result in pneumatoceles (balloon-like lesions that may be filled with air or pus or scar tissue) and very high concentrations of the serum antibody IgE. Inheritance can be autosomal dominant or autosomal recessive. Many patients with autosomal dominant STAT3 hyper-IgE syndrome have characteristic facial and dental abnormalities, fail to lose their primary teeth, and have two sets of teeth simultaneously.

The symptoms are very similar to graft-versus-host disease (GVHD). This is because the patients have some T cells with limited levels of recombination with the mutant RAG genes. These T cells are abnormal and have a very specific affinity for self antigens found in the thymus and in the periphery. Therefore, these T cells are auto-reactive and cause the GVHD phenotype.

A characteristic symptom is chronic inflammation of the skin, which appears as a red rash (early onset erythroderma). Other symptoms include eosinophilia, failure to thrive, swollen lymph nodes, swollen spleen, diarrhea, enlarged liver, low immunoglobulin levels (except immunoglobulin E, which is elevated), low T cell levels, and no B cells.

Nezelof syndrome (also known as Thymic dysplasia with normal immunoglobulins) is an autosomal recessive congenital immunodeficiency condition due to underdevelopment of the thymus. The defect is a type of purine nucleoside phosphorylase deficiency with inactive phosphorylase, this results in an accumulation of deoxy-GTP which inhibits ribonucleotide reductase. Ribonucleotide reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides, thus, DNA replication is inhibited.

A minority of patients are diagnosed with thymoma prior to manifestation of the immunodeficient state. Spindle-cell histology is present in most cases.

Because patients with GS have deficient humoral and cellular immunity, they are susceptible to a wide range of infections. Most commonly these patients suffer from respiratory tract infections. Chronic diarrhea is often related to villous atrophy rather than infection (Kelesidis, 2010).

Often autoimmune disease is associated with GS - most commonly pure red cell aplasia and myasthenia gravis. While the patients may experience hypogammaglobulinemia, a large percentage will have autoantibodies present in their serum (Kelesidis, 2010). It is theorized that the presence of thymoma may inhibit the thymus’s normal role in production of self-tolerant T lymphocytes. These T-lymphocytes may then attack the B cell precursors in the marrow, preventing maturation and ultimately resulting in hypogammaglobulinemia (Arnold, 2015).

Bare lymphocyte syndrome is a condition caused by mutations in certain genes of the major histocompatibility complex or involved with the processing and presentation of MHC molecules. It is a form of severe combined immunodeficiency.

All types of Griscelli syndrome have distinctive skin and hair coloring.

Type 1 is associated with eurological abnormalities. These include delayed development, intellectual disability, seizures, hypotonia and eye abnormalities.

Type 2 - unlike type 1 - is not associated primary neurological disease but is associated with an uncontrolled T lymphocyte expansion and macrophage activation syndrome. It is often associated with the hemophagocytic syndrome. This latter condition may be fatal in the absence of bone marrow transplantation.

Persons with type 3 have the typical light skin and hair coloring but are otherwise normal.
