Treatment in DOCK8 deficiency focuses on preventing and treating infections. Broad-spectrum antibiotics are a common mode of treatment when infection is present, though some infections (like lung abscesses) require surgical treatment. Pneumatocele may be treated with surgery, but the benefit is unclear.

Surgical treatment is also recommended for skin abscesses, along with topical and systemic antibiotics and antifungals.

Long-term treatment with systemic antibiotics, including trimethoprim/sulfamethoxazole, penicillins, and cephalosporins, is effective in preventing skin and lung infections. Other treatments used in DOCK8 deficiency include sodium cromoglycate, which improves white blood cell function, and isotretinoin, which improves skin condition.

Sometimes, Intravenous immunoglobulin is used as a treatment, but its benefits have not been proven. Levamisole is also ineffective. Mixed clinical outcomes have been found with interferon gamma and omalizumab. Though early research on hematopoietic stem cell transplantation was equivocal, later research has shown it to improve immune function. Two patients have been cured by bone marrow transplantation. Cyclosporine A is a current topic of research; preliminary results have shown it to be effective.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

The only treatment for Omenn syndrome is chemotherapy followed by a bone marrow transplantation. Without treatment, it is rapidly fatal in infancy.

In terms of treatment for hyper Igm syndrome there is the use of allogeneic hematopoietic cell transplantation. Additionally anti-microbial therapy, use of granulocyte colony-stimulating factor, immunosuppressants, as well as, other treatments may be needed.

There have been attempts to control the inflammation using drugs that work in other conditions where inflammation is a problem. The most successful of these are steroids, but they have side effects when used long term. Other medications, including methotrexate, colchicine and canakinumab, have been tried with some success. Otherwise, the treatment is supportive, or aimed solely at controlling symptoms and maximizing function.

There is no treatment for NBS, however in those with agammaglobulinemia, intravenous immunoglobulin may be started. Prophylactic antibiotics are considered to prevent urinary tract infections as those with NBS often have congenital kidney malformations. In the treat of malignancies radiation, alkylating antineoplastic agents, and epipodophyllotoxins are not used, and methotrexate can be used with caution and, the dose should be limited. Bone marrow transplants and hematopoietic stem cells transplants are also considered in the treatment of NBS. The supplementation of Vitamin E is also recommended. A ventriculoperitoneal shunt can be placed in patients with hydrocephaly, and surgical intervention of congenital deformities is also attempted.

Currently, no cure for Zellweger syndrome is known, nor is a course of treatment made standard. Infections should be guarded against to prevent such complications as pneumonia and respiratory distress. Other treatment is symptomatic and supportive. Patients usually do not survive beyond one year of age.

Several medications are used to improve bile flow, including ursodiol (Actigall).These medications differ in their rates of success.

Certain drugs may be used to reduce itching (pruritus): hydroxyzine (Atarax), cholestyramine, rifampicin, phenobarbital, and naltrexone. Similar to the medications which improve bile flow, the anti-itching drugs vary in their success rate.

Many patients with Alagille syndrome will also benefit from a high dose of a multivitamin such as ADEK (continuing high levels of vitamins A, D, E, and K), as the reduced bile flow makes it difficult to absorb and utilize these vitamins.

Overall, the prognosis for patients with NOMID is not good, though many (80%) live into adulthood, and a few appear to do relatively well. They are at risk for leukemia, infections, and some develop deposits of protein aggregated called amyloid, which can lead to kidney failure and other problems. The neurologic problems are most troubling. The finding that other diseases are related and a better understanding of where the disease comes from may lead to more effective treatments.

Early treatment is possible once the disease is detected. Once the classical symptoms appear, the best way to eliminate the dangers of Alagille syndrome is a full liver transplant. Most of the short-term treatments available are aimed at improving the functioning of the heart and reducing the effects of impaired liver, kidney, and spleen function.

Children with DOCK8 deficiency do not tend to live long; sepsis is a common cause of death at a young age. CNS and vascular complications are other common causes of death.

The malabsorption resulting from lack of bile acid has resulted in elemental formula being suggested, which are low in fat with < 3% of calories derived from long chain triglycerides (LCT). However, reduced very long chain fatty acids (VLCFA) has not been shown to reduce blood VLCFA levels , likely because humans can endogenously produce most VLCFA. Plasma VLCFA levels are decreased when dietary VLCFA is reduced in conjunction with supplementation of Lorenzo’s oil (a 4:1 mixture of glyceryl trioleate and glyceryl trierucate) in X-ALD patients . Since docosahexaenoic acid (DHA) synthesis is impaired [59], DHA supplementation was recommended, but a placebo-controlled study has since showed no clinical efficacy . Due to the defective bile acid synthesis, fat soluble supplements of vitamins, A, D, E, and K are recommended.

Normal treatment for swelling and any respiratory problems is appropriate. Nutritional supplementation with Vitamin E in some studies has been shown to be effective in controlling nail changes.

CDPX1 activity may be inhibited by warfarin because it is believed that ARSE has enzymatic activity in a vitamin K producing biochemical pathway. Vitamin K is also needed for controlling binding of calcium to bone and other tissues within the body.

Hyperimmunoglobulinemia E syndrome (HIES), of which the autosomal dominant form is called Job's syndrome or Buckley syndrome, is a heterogeneous group of immune disorders. Job's is also very rare at about 300 cases currently in the literature.

The treatment is some form of Vitamin E supplementation.

Aggressive vitamin E replacement therapy has been shown to either prevent, halt or improve visual abnormalities.

People with yellow nail syndrome have been found to have a moderately reduced lifespan compared to people without the condition.

If treatment is initiated early in disease the neurologic sequelae may be reversed and further deterioration can be prevented.

Treatment normally consists of rigorous dieting, involving massive amounts of vitamin E. Vitamin E helps the body restore and produce lipoproteins, which people with abetalipoprotenimia usually lack. Vitamin E also helps keep skin and eyes healthy; studies show that many affected males will have vision problems later on in life. Developmental coordination disorder and muscle weakness are usually treated with physiotherapy or occupational therapy. Dietary restriction of triglycerides has also been useful.

Omenn syndrome is an autosomal recessive severe combined immunodeficiency associated with hypomorphic missense mutations in immunologically relevant genes of T-cells (and B-cells) such as recombination activating genes (RAG1 and RAG2), IL-7 Receptor α gene (IL7Rα), DCLRE1C-Artemis, RMRP-CHH, DNA-Ligase IV, common gamma chain, WHN-FOXN1, ZAP-70 and complete DiGeorge anomaly (DiGeorge Syndrome; CHARGE).

A review from 2000 stated that life expectancy was reduced because of a tendency to develop cancer relatively early as well as deaths due to infections related to immunodeficiency.

There has been no specific drug therapy developed for hepatitis, with the exception of hepatitis C. Patients are advised to rest in the early stages of the illness, and to eat small, high-calorie, high-protein meals in order to battle anorexia. Larger meals are more easily tolerated in the morning, for patients often experience nausea later in the day. Although high-protein meals are recommended, protein intake should be reduced if signs of precoma — lethargy, confusion, and mental changes — develop.

In acute viral hepatitis, hospitalization is usually required only for patients with severe symptoms (severe nausea, vomiting, change in mental status, and PT greater than 3 seconds above normal) or complications. If the patient experiences continuous vomiting and is unable to maintain oral intake, parenteral nutrition may be required.

In order to relieve nausea and also prevent vomiting, antiemetics (diphenhydramine or prochlorperazine) may be given 30 minutes before meals. However, phenothiazines have a cholestatic effect and should be avoided. The resin cholestyramine may be given only for severe pruritus.

Hyper IgM syndromes is a group of primary immune deficiency disorders characterized by defective CD40 signaling; "via" B cells affecting class switch recombination (CSR) and somatic hypermutation. Immunoglobulin (Ig) class switch recombination deficiencies are characterized by elevated serum Immunoglobulin M (IgM) levels and a considerable deficiency in Immunoglobulins G (IgG), A (IgA) and E (IgE). As a consequence, people with HIGM have decreased concentrations of serum IgG and IgA and normal or elevated IgM, leading to increased susceptibility to infections.

Antibiotic creams are the preferred treatment for mild cases of impetigo, despite their limited systemic absorption. Such prescribed ointments include neosporin, fusidic acid, chloramphenicol and mupirocin. More severe cases of impetigo however (especially bullous impetigo) will likely require oral agents with better systemic bioavailability, such as cephalexin. Cases that do not resolve with initial antibiotic therapy or require hospitalization may also be indicative an MRSA infection, which would require the use of agents specifically able to treat it, such as clindamycin.

Antibiotic treatment typically last 7–10 days, and although highly effective some cases of methicillin resistant S. aureus (MRSA) may require longer therapy depending on the severity of infection and how much it has spread.

Hypertension and brachydactyly syndrome (HTNB) also known as Bilginturan syndrome and brachydactyly type E among others is a very rare genetic disorder.

It was first reported in 1973 by N. Bilginturan et al. The estimated prevalence is less than 1 out of 1,000,000.
